There are a lot of urban legends about how to heat and cool your home. One that we hear about at Climate Control Company has to do with getting around the pressure switch on your furnace in Glenwood Springs, Aspen, or Vail, Colorado. Some people think of it as a quick way to fix a broken furnace, but nothing could be further from the truth. First, a quick lesson on pressure switches.
How Do I Bypass My Furnace’s Pressure Switch?
The pressure switch on a furnace serves to safeguard you and your residence. Normally located close to the furnace’s motor, its vital safety functions include sensing negative air pressure, a leading cause of carbon monoxide poisoning. Additionally, this switch is designed to detect gas leaks. In either case, the switch will automatically shut off the furnace. A Relay Is Not A REPA If IRAs with any device, if the pressure switch fails, the furnace will not operate. The issue is that homeowners frequently attempt self-diagnosis or bypass the switch in an effort to restart the furnace.
Climate Control cannot stress enough that bypassing the pressure switch is not maintenance or repair for the furnace. This is merely an attempt to troubleshoot the furnace by isolating the potential source of the issue. Any attempt to get around the system needs to be done by a trained HVAC technician with the right testing tools.
Testing a Pressure Switch
Testing a pressure switch is not a task that most homeowners can perform. To measure resistance (ohms) and voltage, a multimeter and the knowledge to use it correctly are required. The good news is that replacing this system is a relatively straightforward task for an HVAC technician. It is not inexpensive, but it is significantly less expensive than most furnace repairs.
Your furnace’s pressure switch serves as a safety mechanism.
